Pocket Galaxy: Cosmos Sandbox

Build your own universe, then rule it like a god.

Pocket Galaxy is a 3D gravity sandbox where realistic space physics meet total creative freedom. Spawn planets, stars and gas giants, place them in orbit, and watch a living solar system come to life. Then play god with it: heat worlds until they glow, freeze them solid, explode them, or smash them together in stunning destruction.

Often called one of the best universe sandboxes on mobile, it's part relaxing toy, part hands-on physics playground. No levels, no timers, no pressure, just infinite space and your imagination.

WHAT YOU CAN DO

• Build a universe from a huge variety of procedural planets, stars and gas giants

• Simulate realistic gravity and orbital motion in an open 3D sandbox

• Act like a god: heat, cool, explode and smash planets to see what happens

• Unlock new planet types by changing conditions across your solar system

• Follow the planet journal to see how life develops on the worlds you make

• Enjoy rich particles, atmospheres and destruction effects

• Capture and share screenshots of your universe

• Save and load your galaxies anytime

RELAX, CREATE, DESTROY

Nudge an orbit and let gravity take over, engineer a perfectly balanced system, or wipe it all out in a single cosmic collision. The sandbox is entirely yours.
